Using the roskinetic Mavros example as a basis, I'm trying to program autonomous missions for the drone to fly in VIO. However, I can't get a lot of the mavlink commands that depend on local_position_ned to run (i.e. https://mavlink.io/en/messages/common.html#SET_POSITION_TARGET_LOCAL_NED). What mavlink messages/commands do you recommend for flying a drone in VIO?

Have you followed the tutorial at https://docs.modalai.com/mavros ?
